This invention relates to turning mechanism for conveying devices, it particularly relating to mechanism which will guide and feed material whichis passing about a drum or cylinder.

In machines in which material isr carried about a drum or cylinder such as in endless conveyers which pass about a drum, and also in paper and other machineryin which the product is carried by cylinders or drums, it hasbeenusual to provide turning or guiding mechanism arranged about a portion of the" drum or cylinder to prevent displacement of the material passing about the'saine. rThis mechanism is usually, in the form of an endless belt passing over rolls, which is effective forpreventing the displacement of some products, but with 'other products,'

such as wet material" or products molded from paper pulp, it has the effect of dis'- torting the product to such an extent as to preclude the use of such turning means. With belts also, particularly when the products being conveyed about the drum are hot and wet, arapid deterioration lof the belt takes place rendering it useless in a coinparatively short ,time.

The object of our invention is to provide a guiding mechanism of this character which will be simple in construction and effective inthe operation of turning or 'guiding the product about a drumv or cylinderV without distortion of the products and which will be alsoof a character whose life of lusefulness will be unaffected byyheat or moisture.

The particular exemplili'cation of our improvements shown in the drawings is a turning, guiding and feeding mechanism for the drums of endless conveyors, the particular conveyer shown in the drawingsv being for the purpose of carrying products molded from paper pulp, through a drying oven, the

particular. products in this case being what' are known as ats7 foregg fillers which are lmolded-tol a shape to receive the ends of eggs, these flats forming division walls between the cells of the fillers. 1t is to be understood, however, that our invention is not limited to this particular kind of conveying apparatus, nor in fact to endless conveying devices, butpmay be successfully einployed in connection with drums or cylinders in other kinds of machinery which carry material or products aboutthe same aiidavhich require some provision for retaining the material or products thereon. ln the accompanying drawings:

F ig. 1v is a Aside elevationof a portion of i 2 is a section*V on the lineA 2-2of y.

3, this drum being keyed to the shaftmlfr'` which is driven from any suitable source of power. The.' chains 1 run about sprocket wheels 5 also keyed to the shaft. Vertical standards r6 support` the shaft and these standards also form the support for our improved guiding and feeding devices to be now described.

Secured to the uppery end of each standard is a bracket 7, this bracket being formed l on the arc of a circle to provide a support concentric to the axisA of the drum. The

bracket has an integrally formed arm 8, the

under surface'of which has a tonguey 9 which tits a groove formed in the upper endv of thestandard 6, and bolts 10 secure the arm to the standard. V'lhe'openings through the armare elongated, as indicated in dotted vlines at 8 to permitthe necessary adjustment to bring-the gearsproperly in mesh.

Mounted in suitable bearings in these brackets 7 are a "seriesV of rolls 11, six of these rolls being employed in the present installation. Each roll is provided with la pin'- ion'12 which is in mesh with a gear 13 keyed te t-hesheft/i; L g v L Also supported bythe brackets are a series 'of curved guide strips 15, three in number in.

the present case. These guide strips extend between the rolls 11 land the drum, the rolls .v

being formed with a series of peripheral grooves 16 to accommodatey the strips. To

support the strips, each strip is provided with a plurality of arms 17 which are at-` tached to cross bars 18 secured to lugsl 19 formed integrally with the brackets. Those ends of the guide strips 15 which face the vapproaching product or material carried by the conveyer are preferably upturned as in- .l

dicated atv 15.

In operation, with the parts moving inthe direction of the arrow shown in Fig. l, the product P carried by the conveyer as it passes about the drum is received by the rotating guide and feed rolls and curved guide strips and` retainedv on the conveyer during its passage about the drum without distortion of the products, the rolls acting not only to guide the material but also to assist in feeding the same by coacting with theV moving conveyer. The guide strips l54 serve to hold the product to the coiiveyer at those points between the rolls. Y guide strips may be made of any suitable materialto resist heat and moisture, being preferably constructed of metal', so that little orne deterioration' ofthe turning mechanism occurs'as'wou'ld be the case with belts constructed of leather, fabric or similar material.

After the product leaves the turning mechanism, itl is deposited upon another con'- veyerl andconveyed back through the drying oven orother suitable point.

IIaving thus described our invention, we claim: g
